Title: New halotriazinylamino-monoazo dyestuffs and processes for their manufacture and use
IPC: C09B62/08
Filed: 1963-11-13
Abstract: The invention comprises dyestuffs of formula R-N=N-R1-X wherein R is the residue of a naphthalenetrisulphonic acid, R1 is a benzene residue bound to the azo group in p-position to group X, and X is the residue of a 4-halo-1,3,5-triazine bound in 2-position through an amino bridge, which group X carries the residue of a 1 - aminoanthraquinone - 2 - sulphonic acid bound in 6-position through an amino group. The dyes are prepared by condensing the corresponding aminoazo dye and 1-amino-anthraquinone-2-sulphonic acid with a tri-halo-triazine. The dyes may be used to colour wool, silk, leather and synthetic polyamides but are preferably used to colour cellulose fibres by the usual reactive dye processes in green and brown shades. Examples describe the preparation of the dyes.  Specifications 797,946 and 992,558 are referred to.

Patent GB-1594338-A (GB)
Title: Production of an article from fibre reinforced synthetic plastics materials
IPC: B29C43/12
Filed: 1977-11-01
Abstract: In a method for producing large structural components such as boats or swimming pools of fiber reinforced synthetic materials layers of pre-impregnated fiber material are continuously applied to a mold. An air impermeable foil or membrane is sealed over the layers of pre-impregnated fiber material. The air is evacuated between the foil or membrane and the fiber material to press the latter by atmospheric pressure against the mold to cause the material to conform to the shear surfaces of the mold. The layers of pre-impregnated fiber materials are then heat cured by heated mats, for example, similar to electric blankets. The sheer surfaces of the molding apparatus are made of sheet material such as sheet metal or sheets of synthetic material. The pressure application and heat curing takes place sequentially in area after area whereby the final size of the finished structure is not limited by the size of an autoclave nor is it limited by the size of available heating blankets.

Abstract: 1328420 Discharging endless belt conveyers AMERICAN METAL CLIMAX Inc 6 Oct 1971 [19 Oct 1970] 46489/71 Heading B8A Material on an endless belt is discharged by inverting the trough-like conveying run of the belt. A belt 10 normally has its top run supported on troughing idlers 14 and by the crowns 44 of a plurality of rollers 20 when the latter are in their lowered position. To discharge material at intervals along the conveyer a number of the rollers 20 are raised by mechanisms 22 such that the belt has its centre position lifted and material falls down sides 42 of the belt into bins 46 or into shoots. To aid discharge the belt is agitated due to eccentric mounting of the rollers 20 and by providing the rollers with axial ribs. In addition a brush or plough 72 is provided at each discharge station. A dust hood 76 covering the entire conveyer has access panels. The rollers 20 are raised by hydraulic cylinders 62 and these may be actuated in a predetermined sequence under the control of a programmer (88), Fig. 10 (not shown). In a modification, Fig. 8, the mounting of the roller 20 is stationary and the mounting of the troughing idler 14 is vertically movable to provide inversion of the trough. The discharge operation may be mechanically or electrically controlled.

Abstract: 1,113,245. Synchronous machines; control of A.C. motors. ENGLISH ELECTRIC CO. Ltd. 1 March, 1965 [29 Nov., 1963], No. 47317/63. Headings H2A and H2J. A 3-phase synchronous machine, which is to be connected to an A.C. supply system for power factor correction, has its rotor mechanically coupled to the rotor of a second A.C. machine. On starting, the second machine is started as a normal wound rotor induction motor and is synchronized with the supply by connecting the rotor windings to a D.C. supply which is then varied to angularly displace the rotor field and thereby physically displace the rotor of the machine relative to the rotating field of the supply to a position where the synchronous machine can be connected to the supply with minimum disturbance. The second machine has a rotor with three windings 14, 15, 16 which are connected through a changeover switch 17, in one position, to resistors (not shown) for induction motor starting and, in the other position, to two exciters 19, 20 which supply D.C. current to the rotor winding for synchronous running. In the run position the rotor windings are connected in star by means of contacts 21 and exciters 19, 20 are connected between the ends of windings 15, 14 and 16, 14 respectively. By differentially varying the output voltages of the exciters the resultant rotor field may be rotated through an angle of 60 degrees about a mean position where both exciters are giving equal outputs. By connecting exciters 19, 20 across windings 14, 16; 15, 16 respectively the mean position may be rotated by 120 degrees and by making the third connection (16, 15, 14, 15) and by reversing the polarity of the exciters at each connection a full 360 degrees movement of the rotor field vector can be obtained. Alternatively a D.C. voltage can be independently supplied to each rotor winding and the value adjusted so that they bear the same relationship to each other as the phase voltages in a 3-phase system.

An isothermal thermocouple calibration apparatus of the type described in Specification 1,014,418 has at least two elongated tubes 9 joined at their closed ends by a metallic member 10 of good thermal conductivity. The member may seal the tube ends or they may be capped separately. The tubes are immersed in water or other media filling a copper chamber 5, 6 cooled by the cold junction of thermo-electric devices 11, 12 the hot junctions of which are mounted on heat sinks 13, 14. Formation of a determined volume of ice causes a bellows 21 to expand and cut-off or reverse the current to the devices through a micro-switch 19. If a low critical degree of freezing is required, the switch may be optionally shunted when the initial water temperature is too high. The bellows is arranged so that it is not fully extended when the chamber is filled with ice. The compositions of suitable materials for the tubes and chamber are given in the Specification. An outer split casing 1, 2 is partly filled with heat insulation material.
